Parts for Volvo Penta marine diesel and petrol engines, such as the Aquamatic series, have always been the cornerstone of PoseidonMarine. Due to our experience and customer pool, in our store you will be able to find most, if not all, consumables like: crankcase filters, fuel filters, air filters, spark plugs, impellers, trim cylinder components, exhaust elbows and manifolds, and more. Besides these parts, we have assembled specialised per-engine type overhaul kits that have parts from the most renowned suppliers like Recmar, SLP, Mahle, and more. Apart from the overhaul kits, you can find complete maintenance kits for Volvo Penta, petrol, and diesel alike. 

 

Poseidon Marine has an extensive stock of engine gasket kits for engines like: AQ125A, AQ271C, AQ131C, AQ151, and B230. We also have innovative repair kits like the circulation pump repair kit for the AQ165, AQ170 six-cylinder Volvo Penta Gasoline engine “PoseidonMarine® Circulation pump repair kit Volvo Penta AQ165 AQ170 831742 831720”. Taking into account the labour required to perform such repairs, we have managed to source the best suppliers of the market, who can offer top-quality parts. SLP and Crom Marine are two Swedish manufacturers that supply us with their gasket sets.

 

Another important group of parts of this section are the drive parts. Statistically, the drive is the most exposed part to the harsh conditions. Consequently, the replacement of its components happens at a faster rate compared to other parts. Here you can find propeller unit seals, various drive O-rings, universal joints (U-joints), rubber bellows, and other more specialised parts for your Volvo Penta outdrives. When it comes to the bellows of your Volvo, the balance between the quality and the price is very delicate. A poor-quality u-joint bellows can put you in big trouble and create very costly problems. PoseidonMarine strongly suggests the bellows manufactured by the Italian company CEF and the Swedish SLP. CEF is worldwide known for its superior rubber components, while SLP creates products equal to or better than the OEM. Who else gives a 3-year warranty?

 

Our company’s strength has always been Volvo Penta Marine Diesel parts. This is the reason you can find almost everything for Volvo Penta AD41, AQAD41A, KAD43, KAD300, and KAMD300. Our inventory has expanded to the newer series, Volvo Penta D4 and Volvo Penta D6. That is why you expect to find in stock overhaul kits, cylinder head repair kits, cylinder liner kits, engine valves, main and big-end bearings, injector sleeve kits, and valve seats. Our preferred suppliers for these parts are: SLP, Recmar, Crom, and private imports from Turkey. Other than the popular series mentioned just before, PoseidonMarine has an extensive stock of rarer parts for older series, like: Volvo Penta MD11, MD17, MD1, MD2, MD3, MD21, AQD21, MD21, TAMD30A, and TAMD40A.

 

We find it important to mention that we have our own production line of branded trimming components. The PoseidonMarine trimming parts include: trim cylinder ram, and cap kits for the most popular cylinders, like the following: 872612, 3860881, 3857470,  3885196, 3888301, and 21840807. We have also developed a new hydraulic manifold for the SX series, to cope with the demand due to the many crossed threads “Poseidon Marine® Hydraulic Manifold Block for Volvo Penta SX replaces 3852559”. 

The second cornerstone of PoseidonMarine is the water pump repair kits, whether intended for the seawater pump or for the circulation pump. All of our kits are supplied with high-quality bearings, like SKF, Nachi, KOYO, INA, or other companies of the World Bearing Association. Therefore, if the repair is done properly, it will last as long as a new pump. 

 

Our parts are already known to the USA, every Balkan and European country, and even in Australia and New Zealand. A reverse search on various boating forums will verify our statement; the customers’ comments act as a testimonial to our quality standards. We offer parts for Volvo Penta marine in the USA and to the whole world. See other popular parts purchased for Volvo Penta engines: 

 

Sea water pump for Volvo Penta TMD TAMD KAD KAMD replaces 3583115 3581558

 

• Accessibility: The seawater pump is located on the front side of the engine, and it is usually quite easy to access, unless you have a tight engine room.
  
  

• Water Leaks: The water pump 3583115 should be installed using a new mounting o-ring with part number 968971. The lower hose is the water intake, and the upper hose supplies water to the oil cooler. The hose clamps should be tightened properly to avoid any leaks. The impeller of the pump 3841697/09-1028B should be changed every season, or every 500 hours. It is recommended the change the water seals 827247 at the same time.
  
  

• Signs my water pump needs repair: One of the most obvious signs your 3583115 needs service is the water pump dripping. This is usually an oil seal (#827247) and a water pump O-ring change. If the pump makes a wobbly sound during its function, it may be due for a new bearing kit. If you notice deep marks on the shaft at the oil seal area, you will need a new shaft. Even if you put new oil seals, the small groove will damage them faster, leading to a new leak. After all, even the shaft is a water pump consumable, with a lifecycle of 1500-3000 hours. We offer an A-Z solution, covering all essential and supplementary parts to renovate your old Volvo Penta part, and make it like new: “PoseidonMarine® Sea Water Pump Repair kit Volvo Penta diesel 3583115 10-24524”

 

PoseidonMarine® Trim Cylinder Rebuild kit Volvo Penta DPH DPR 21840806 21840807

 

 

• Accessibility: The trim cylinders can be easily accessed when the boat is out of the water. One side of the cylinder is attached to the outer part of the lower unit, while the other side is supported on the transom plate.
  
  

• Fluid Leaks: The trim cylinders 3887960, 3888301, 21840806, 2180807, and 22121309 may start leaking hydraulic fluid from the pressure seal. This seal keeps the oil inside the cylinder and helps maintain the required pressure.

• Signs my cylinder needs repair: One of the most obvious signs that your trimming cylinder needs repair is the ATF fluid leak. This usually starts as a very slow leak, and you may not notice it when you are in the water, unless the rate of loss worsens. Another evident problem is the inability to maintain the “TRIM UP” position. This usually happens when the piston seal is significantly worn, thus the cylinder cannot maintain the required pressure, and your drive moves down. The fix is easy, and you will need a “PoseidonMarine® Trim Cylinder Rebuild kit Volvo Penta DPH DPR 21840806 21840807”. If your ram has deep grooves, we also recommend changing it with a new one,”PoseidonMarine® Trim Cylinder Ram for Volvo Penta DPH DPR 3888301 21840806”.

SLP® Intercooler insert for Volvo Penta D31 D32 D41 D42 D43 D44 3582599

 

 

• Disassembly difficulty: During the process of disassembly, you may find challenges, especially if the aftercooler has not been maintained for a long time. Additionally, the aluminum housing is prone to corrosion and relatively easy to damage. As soon as the hoses are removed from the housing, you may start loosening the 12 nuts holding the housing together. The application of an anti-rust agent like WD-40 is suggested before starting the process. Remove the cover carefully without damaging the 12 studs – a gentle sideways motion may help it get unstuck. Remove the old gasket, and lift up the aftercooler insert.
  
  

• Core cleaning or replacement: Having torn your aftercooler apart brings you the chance to clean its core. If the air cells of your core are very oily, you probably have a problem with your turbo. The proper way to clean the core is to leave it overnight in a mix of ½ liter 35% vinegar concentrate diluted with 3.5L of water. The next day, rinse with a lot of soap water. All mating surfaces must be meticulously cleaned so that they are free of oil or other contaminants; failing to do so may lead to improper sealing. If you use a more concentrated acid, remember that you always pour the acid into the water, never the other way around; otherwise, an exothermic reaction will be initiated. An outdoor place, or a properly ventilated is preferred, as well as using basic protection, like latex gloves and eye protection. Having said the core is made of aluminium, there might be excessive corrosion due to neglect of maintenance. At that point, PoseidonMarine recommends the SLP products, with a warranty period of 3 years. One option is “SLP® Intercooler insert for Volvo Penta D31 D32 D41 D42 D43 D44 3582599”. If your engine is a D300, you will need the alternative reference “SLP® Charge air cooler for Volvo Penta KAD300 KAMD300 3583101”.
  
  

• Seal Placement: Make sure that all the mating surfaces are clean and free of any contaminants, in order to achieve a proper sealant. The seals are installed dry, without the addition of any glue or oil. The gasket set 876110 contains all necessary seals to reinstall the aftercooler inserts 3582599 and 3583101. The two rectangular gaskets 860920 are sealing the insert into the housing, the sealing strip with reference 847573 is placed under the top cover, and the reference 3582639 is used on the lower side. For the coolers that use a quick hose connection, four O-rings with reference 858986 are included. PoseidonMarine offers a complete gasket kit with reference: “Aftercooler seal kit for Volvo Penta D31 D32 D41 D42 D43 D44 similar 876110 877386”.

 

Crom® Shift Actuator Seal kit Volvo Penta 853868 O-ring 925093 18-2068

 

 

• Accessibility: The shift actuator is located on the propeller side of the upper part of the drive. As soon as you remove the plastic cover, you will see a 4-bolt plate – there is the shift actuator.
  
  

• Oil Leaks: If there is an oil leak, the shift actuator seal 853868, along with its sealing O-ring 925093, must be replaced. 

• Preventive maintenance: The shift actuator must be inspected at the beginning of every boating season. If the plunger 3856008 is worn, it must also be replaced; otherwise, it will leak soon after you install a new 853868 seal. We offer a quality replacement for the eccentric piston “Recmar® Shift Actuator eccentric piston plunger 3856008”.

Recmar® Stainless steel Exhaust Elbow Volvo Penta 31 32 41 42 43 44 300 861289

 

 

• Accessibility: The exhaust elbow is mounted on the turbocharger.
  
  

• Corrosion and Seizing: All cast iron elbows suffer from corrosion and seizing, especially if the elbow is not dismounted and cleaned regularly. Additionally, a neglected elbow will have accumulated carbon deposits, which will accelerate the corrosion and reduce the flow of the exhaust gases, leading to performance issues and direct corrosion to the turbocharger.

• Stainless steel solution: A stainless steel elbow, like this “Recmar® Stainless steel Exhaust Elbow Volvo Penta 31 32 41 42 43 44 300 861289” does not corrode, therefore does not accumulate carbon. PoseidonMarine offers stainless steel elbows for many different Volvo Penta marine diesel engines, all made of 316L stainless steel.

 

Poseidon Marine® Hydraulic Manifold Block for Volvo Penta SX replaces 3852559

 

 

• Accessibility: The manifold 3852559 is located inside the transom shield, attached to a stud.
  
  

• Corrosion and damage on the threads: The trim block distributor is regularly very corroded, due to its constant exposure to the water. Additionally, its fine threads are easily damaged during the removal/installation of the trimming hoses.

• Solution: Since the manifold is very small to repair the damaged threads, PoseidonMarine offers a brand new manifold, at a very affordable price, identical to the OEM: “Poseidon Marine® Hydraulic Manifold Block for Volvo Penta SX replaces 3852559”.

 

SLP® Cone Clutch Sliding Sleeve for Volvo Penta DP drives 3807613 3852293

 

 

• Accessibility: The sliding sleeve is located inside the upper gearhousing.
  
  

• Shifting difficulties: If the problem is not related to incorrect adjustment, then the sliding sleeve might be the cause of rough shifting or inability to shift.

• Solution: PoseidonMarine offers sliding sleeves for different Volvo Penta drives, like the following:
  “Volvo Penta® Sliding sleeve 873098 sail drive MS2”
  “SLP® Cone Clutch Sliding Sleeve for Volvo Penta DPH DPR drives 3849006”
  “SLP® Cone Clutch Sliding Sleeve for Volvo Penta DP drives 3807613 3852293”
  This is a very crucial component, so OEM or SLP is preferred. When the cone is changed, it is mandatory to change the shoe to achieve parts with equal wear. Uneven wear will cause premature failure or rough shifting.
